A quick park and grab. Great for the kids. Quiet after hours and on Sundays.
This cache is located near my place of work. The container is molded from two peices of a core sample. The core samples we take are used to determine the compressive strength of concrete. They are put under great loads until they break and that breaking point is its strength. 32Mpa or 4641 PSI is a most commonly used concrete for driveways and sidewalks.Please bring own writing stick as only the log fits. Happy Caching
Congrats to Switty 13 for FTF!
